BUTTON-FEEDING MECHANISM.

Application filed. September 28, 1916.

To all whom it may concern:

Be it known that I, Lona E. PooLn, a citizen of the United States, and a resident of Anderson, county of Madison, and State of Indiana, have invented a certain new and useful Button-Feeding Mechanism; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like letters refer to like parts.

This invention relates to an improvement in machines for feeding and attaching buttons. It has for its object to provide a machine of this class with a means for feeding buttons from the hopper to the chute, which is mechanically operated, special reference being had to my former Patent No. 1192682 for button attaching machine issued July 25, 1916, and my application for button feeding mechanism Serial 49280, filed September 7, 1915.

The main feature of this invention is a compensating mechanism on the button elevator or feeding plate which operates in the button hopper, which mechanism allows a certain compensation of movement of the feeding plate actuated so that the continued movement of the actuating means will be taken up when the feeding plate reaches its highest position, which does away with the sudden stopping or jarring of the plate when it reaches its limit of movement, which in many cases causes the buttons elevated thereby to be thrown off. The mechanism which is hereinafter described is adapted to take up and compensate for the continued movement of the actuating means after the feeding plate has reached its limit of movement and is in position for the buttons to slide down the button chute.

-The full nature of this invention will be understood from the accompanying drawings and the following description and claims. a

In the drawings Figure 1 is a side elevation of the machine. Fig. 2 is a central vertical cross section with parts broken away. Fig. 3 is the same as Fig. 2, showing the device in operative position. Fig. 1 is a view taken on line H of Fig. 1.

In the drawings there is shown a pedestal having a table on which the mechanism is mounted, said table being secured to base 11 by means of a hollow tube. A foot ped Specification of Letters Patent.

Patented June 5, 1917.

Serial No. 122,734.

estal 12 is fulcrumed on the base at 13 and pivoted at 14 to a rod 15 extending through the hollow tube to cam disks 115 and pivoted thereto at 16. Said cam disks are mounted in frame 17 on the pin 18, and are held in operative position by means of a spring 19 secured at its lower end to the hollow tube and at its other end to a rod 20 pivoted on said disks.

Secured to the frame of the machine there is a hopper 22 adapted to receive a supply of buttons which it is desired to have fed into the machine. A feeding plate or elevator 23 operates through the-bottom of said hopper. There is a slot 24: in the upper end of said plate for carrying the buttons in the hopper and arranging them preliminary to feeding the machine. Said plate is yieldingly held to the table by a rod 124; extending therethrough and having a spring 25 below the table for resisting its upward movement, and a spring 26 above the same for limiting the downward movement of said feeding plate, said springs being adapted to act as cushions. Pivoted to the lower end of said plate and at one corner thereof there is an arm 27 which is provided with a groove 28 which has an upward projecting toothlike member 29 in the center thereof. Extending into said groove and over said projection there is a spiral spring 80 which extends upwardly within said feeding plate. Said feeding plate is provided with two side plates 31 between which the arm 27 is pivoted and the spring extends. A central plate 32 is secured between said plates for spacing them apart, said plate being cut away at the bot-tom as shown in drawings so as to permit the arm 27 to extend upwardly therein when the mechanism is at its highest point of movement.

Extending from the cam disks 115 are arms 33 between which is pivoted a roller 34- which is adapted to engage the arm 27 and force it upward as the cam disks are operated.

The advantage of this compensating mechanism is that by means of the tension of the spring 30 the feeding plate is at first moved slightly upward until the spring reaches such a tension that the plate moves with the upward movement of the cam disks until it reaches an elevation where the slot 24 is in alinement with the button chute where it stops, and all further upward Fal movement of the cam disks is taken up and compensated for by the spring 30, which prevents a final jolt or jerk from being imparted to the plate. a

The invention claimed is:

1. A button attaching machine including a frame, a button chute, a button hopper at one end of said chute, a feeding plate adapted to be operated in said hopper, a spring extending upwardly therein, an arm pivoted in the lower end of said plate so asto engage said spring, and means on said machine for engaging said arm whereby said plate will be operated.

2. A button attaching machine including a frame, a button chute, a button hopper at Copies of thispatent may be obtained for five cents each, by addressing the Commissioner of Patents,

one end of said chute, a feeding plate adapted to be operated in said hopper, a spiral spring extending upwardly through the bottom of said plate, an arm pivoted to said plate having a recess therein, a tooth extendnesses herein named.
